Description

Technical Field

[0001] This utility model relates to the field of personal care equipment, specifically to a lens connecting tube, a lens connecting tube connecting kit, an oral observation mirror, and a visual ear pick for personal care. Background Technology

[0002] With increasing health awareness, the use of personal care tools (such as ear picks and oral endoscopes) is becoming more and more widespread, and users are placing higher demands on their safety, convenience and comfort.

[0003] Currently, the handles and spoons of most ear picks are rigid structures. However, the human external auditory canal has a physiological curvature of about "S". When using an ear pick, users often need to twist their wrists or tilt their heads to a large extent to reach the earwax deep in the ear canal. This is clumsy and tiring. Furthermore, hard ear picks can easily scratch the delicate skin of the ear canal and may even pose a potential risk of accidentally damaging the eardrum, resulting in a poor user experience.

[0004] Similarly, some dental endoscopes used to observe the condition of teeth in the oral cavity often require users to make frequent and significant adjustments to the handle angle when observing complex areas of the oral cavity, or require users to adopt specific and potentially uncomfortable mouth-opening postures to facilitate observation. This operation is not only inefficient and time-consuming, but also easily triggers discomfort such as nausea in patients, greatly affecting the convenience and comfort of operation.

[0005] To address this, a lens connecting tube for personal care, a lens connecting tube connection kit, an oral observation mirror, and a visual ear pick are provided to reduce the difficulty and force required for operation, and to improve safety and comfort. Utility Model Content

[0033] The present invention will now be described based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail, but well-known methods, processes, procedures, and elements are not described in detail in order to avoid obscuring the essence of the present invention.

[0034] Furthermore, those skilled in the art should understand that the accompanying drawings provided herein are for illustrative purposes only and are not necessarily drawn to scale.

[0035] Unless the context explicitly requires it, the words "comprising," "including," and similar terms throughout the specification and claims should be interpreted as encompassing rather than being exclusive or exhaustive; that is, meaning "including but not limited to."

[0036] In the description of this utility model, it should be understood that the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance. Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0037] To improve the bending flexibility of the lens connector tube while ensuring safety, and further enhance its usability, this embodiment discloses a lens connector tube for personal care. This lens connector tube is designed for daily personal care, meaning users can use it independently in their daily lives without the assistance of medical personnel. Please refer to... Figure 1 , Figure 1This is a schematic diagram of the structure of a lens connecting tube disclosed in this embodiment. The personal care lens connecting tube includes a tube body 10 for supporting a flexible sleeve. The tube body 10 is disposed inside the flexible sleeve and serves to support it. A flexible sleeve is provided on the outside of the tube body 10, enabling protection of the tube body 10. In specific implementations, the tube body 10 can be made of a nickel-plated metal material, such as stainless steel, aluminum, or iron.

[0038] The pipe body 10 has a plurality of first notches 11 and a plurality of second notches 12 arranged circumferentially, wherein the first notches 11 and the second notches 12 are staggered in the circumferential direction of the pipe body 10. In this embodiment, the staggered arrangement of the first notches 11 and the second notches 12 can be staggered in opposite directions in the circumferential direction of the pipe body 10, or staggered in a lateral direction in the circumferential direction of the pipe body 10. Preferably, the staggered arrangement of the first notches 11 and the second notches 12 refers to a relative staggered arrangement.

[0039] The opening direction of the first notch 11 is at least partially opposite to the opening direction of the second notch 12, and the first notch 11 and the second notch 12 are not connected, so that the tube 10 can be bent in the opening direction of the first notch 11 and / or in the opening direction of the second notch 12. The width of both the first notch 11 and the second notch 12 is less than a preset distance to limit the bending angle of the tube 10 in the opening direction of the first notch 11 or the opening direction of the second notch 12. By providing the first notch 11 and the second notch 12 in different directions of the tube 10, and by limiting the width of the first notch 11 and the width of the second notch 12, it is possible to provide a deformation range for the bending of the tube 10, while preventing the tube 10 from breaking due to excessive bending.

[0040] The statement that the opening direction of the first notch 11 and the opening direction of the second notch 12 are at least partially opposite means that the angle between a straight line along the opening direction at the center of the first notch 11 and a straight line along the opening direction at the center of the second notch 12 is greater than 90°. In other words, it is not required that the first notch 11 and the second notch 12 be perfectly aligned; as long as their opening directions are partially opposite, it is sufficient to provide deformation space for the bending of the pipe body 10. For example... Figure 2 As shown, Figure 2 This is a partial schematic diagram of another structure of a lens connecting tube disclosed in this embodiment. Figure 2 As shown, the opening direction of the first notch 11 and the opening direction of the second notch 12 are not completely opposite to each other.

[0041] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of a lens connecting tube when bent, as disclosed in this embodiment.

[0042] like Figure 1 As shown, both the first notch 11 and the second notch 12 have a width of a preset distance. The width of the first notch 11 refers to the width of the opening of the first notch 11, and the width of the second notch 12 refers to the width of the opening of the second notch 12. It can be understood that the first notch 11 and the second notch 12 can have the same width or different widths. Preferably, the first notch 11 and the second notch 12 have the same width.

[0043] like Figure 3 As shown, during the bending of the tube 10 towards the opening of the second notch 12, when the opening of the second notch 12 is squeezed until the two ends of the opening touch (that is, when the opening of the second notch 12 is close to being closed), the bending angle of the tube 10 in the direction of the opening of the second notch 12 reaches its maximum. During this process, the opening of the second notch 12 is continuously squeezed to approach closure, while the opening of the first notch 11 is stretched open. By setting the width of the first notch 11 and the width of the second notch 12, a certain deformation range can be provided for the bending of the tube 10, while preventing the tube 10 from breaking due to excessive bending.

[0044] Similarly, during the bending of the tube 10 towards the opening of the first notch 11, when the opening of the first notch 11 is squeezed until the two ends of the opening touch (that is, when the opening of the first notch 11 is close to being closed), the bending of the tube 10 in the direction of the opening of the first notch 11 reaches its maximum bending angle. During this process, the opening of the first notch 11 is continuously squeezed to approach closure, while the opening of the second notch 12 is stretched open. By setting the width of the first notch 11 and the width of the second notch 12, a certain deformation range can be provided for the bending of the tube 10, while preventing the tube 10 from breaking due to excessive bending.

[0045] In the specific implementation process, the first notch 11 and the second notch 12 can be discontinuously set on the pipe body 10. That is to say, the first notch 11 and the second notch 12 can be staggered only in the part of the pipe body 10 that needs to be bent, and it is not necessary to require the entire pipe body 10 to be provided with the first notch 11 and the second notch 12.

[0046] In an optional embodiment, the opening width of the first notch 11 and / or the second notch 12 is 0.3mm to 3mm, and the spacing between each first notch 11 and / or second notch 12 is 0.5mm to 5mm. It is understood that the spacing between multiple first notches 11 is 0.5mm to 5mm, and the spacing between multiple second notches 12 is also 0.5mm to 5mm. The specific value of the spacing between multiple first notches 11 can be different from or the same as the specific value of the spacing between multiple second notches 12. By limiting the opening width of the first notch 11 and the second notch 12 and the spacing between them, the bending angle of the tube 10 is controlled, thereby enabling the tube 10 to bend within a preset range and preventing the tube 10 from breaking due to excessive bending.

[0047] In an optional embodiment, the first notch 11 and / or the second notch 12 are arranged radially along the tube body 10. In this embodiment, the opening direction of the first notch 11 is radially along the tube body 10, and the opening direction of the second notch 12 is also radially along the tube body 10. Compared to the arrangement where the first notch 11 and the second notch 12 do not open radially along the tube body 10, this allows the first notch 11 and / or the second notch 12 to provide greater deformation space for the tube body 10 when it is bent, thereby enabling the tube body 10 to have a greater bending range.

[0048] In an optional embodiment, the first notch 11 and / or the second notch 12 are evenly spaced along the circumference of the tube body 10. In this embodiment, evenly distributing the first notch 11 and the second notch 12 along the circumference of the tube body 10 means that the first notch 11 and the second notch 12 are interleaved, and there is a uniform interval between each first notch 11 and its two adjacent second notches 12, and a uniform interval between each second notch 12 and its adjacent first notch 11. Evenly distributing multiple first notches 11 and multiple second notches 12 along the circumference of the tube body 10 provides uniform deformation space in each segment of the tube body 10, thereby enabling each segment of the tube body 10 to bend at multiple angles.

[0049] In an optional embodiment, the first notch 11 and the second notch 12 are disposed opposite to each other on the tube body 10. That is, the opening direction of the first notch 11 is opposite to the opening direction of the second notch 12. When the tube body 10 is bent, the first notch 11 and the second notch 12 disposed opposite to each other can provide the tube body 10 with a larger deformation space, so that the tube body 10 has a larger bending range and is more flexible in use.

[0050] Please see Figure 4 , Figure 4 This is a schematic diagram of another tube structure in a lens connecting tube disclosed in this embodiment. Figure 4As shown, in an optional embodiment, the tube body 10 is further provided with a plurality of third notches 14 along the circumferential direction. The first notch 11, the second notch 12, and the third notch 14 are staggered in the circumferential direction of the tube body 10, and the third notch 14 is not connected to either the first notch 11 or the second notch 12. In this embodiment, the tube body 10 is also provided with a third notch 14 in another direction, thereby enabling the tube body 10 to bend in the opening direction of the third notch 14, providing the tube body 10 with more bending directions and improving the flexibility of bending the tube body 10.

[0051] Understandable, such as Figure 4 As shown, a fourth notch 15 can also be provided circumferentially on the pipe body 10. Preferably, the fourth notch 15 can be arranged opposite to the third notch 14. Similarly, the first notch 11, the second notch 12, the third notch 14, and the fourth notch 15 are staggered in the circumferential direction of the pipe body 10, and the third notch 14, the fourth notch 15, the first notch 11, and the second notch 12 are not connected to each other. By providing multiple non-connected notches on the pipe body 10, the pipe body 10 can be bent at multiple angles, providing more bending directions for the pipe body 10 and improving the bending flexibility of the pipe body 10.

[0052] In an optional embodiment, one end of the tube 10 is further provided with a connecting portion 13 for connecting a nursing accessory. In specific implementations, the nursing accessory can be a personal care device, such as the tip of an ear pick, a viewing lens, etc. The connecting portion 13 can be fastened to the nursing accessory by snap-fit ​​or by thread. Furthermore, the connecting portion 13 and the nursing accessory can be directly connected or indirectly connected through other components. The detachable fastening connection between the connecting portion 13 and the nursing accessory allows the tube 10 to connect to different external devices, thereby enriching the application scenarios of the tube 10.

[0053] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the connection structure between the lens connecting tube and the connecting kit disclosed in this embodiment. Figure 6 This is a schematic diagram of the connection kit for a lens connecting tube disclosed in this embodiment. Figure 5 and Figure 6 As shown in the illustration, this embodiment also discloses a lens connecting tube connection kit, such as... Figure 5 As shown, the lens connecting tube connection kit 20 includes a fixing component 21, one end of which is fixedly connected to the connecting part 13, and the other end of which is fixedly connected to the care accessory.

[0054] In this embodiment, the fixing component 21 can be fixedly connected to the connecting part 13 by various methods such as snap-fit, adhesive, welding, etc. The other end of the fixing component 21 can be fixedly connected to the nursing accessory by various methods such as threaded connection, snap-fit ​​connection, etc., without specific limitations.

[0055] In practical implementation, a functional module, such as a camera module, can be set inside the fixing component 21. Then, the tube body 10 and the nursing accessories are connected through the fixing component 21. This ensures that the tube body 10 can be bent freely at multiple angles, and also ensures that the internal functional modules are not damaged when the tube body 10 is bent. In practical implementation, the fixing component 21 may include one or more components.

[0056] In the specific implementation process, such as Figure 5 As shown, the functional modules within the connecting kit 20 are electrically controlled via a flexible FPC 16 disposed within the tube body 10. When the tube body 10 has opposing first notches 11 and second notches 12 to allow bending in two opposing directions, the flexible FPC 16 within the tube body 10 can either be attached to the first notch 11 or the second notch 12 and parallel to it, or it can be suspended in mid-air (e.g., ...). Figure 5 The diagram shows a suspended flexible FPC (as illustrated in the image), ensuring that the flexible FPC 16 is not damaged when the tube 10 bends towards the second notch 12 or the first notch 11. When the tube 10 has the first notch 11, the second notch 12, the third notch 13, and the fourth notch 14 to allow bending in four directions, the flexible FPC 16 inside the tube 10 is suspended and not in contact with any of the notches, thus ensuring that the flexible FPC 16 is not damaged when the tube 10 bends in any direction. It is understood that regardless of whether the tube 10 bends in two or four directions, the flexible FPC 16 needs to have a certain length redundancy within the tube 10 to prevent the flexible FPC 16 from being pulled when the tube 10 bends, thereby protecting the flexible FPC 16.

[0057] In the specific implementation process, such as Figure 4 As shown, the fixing component 21 includes a plug 211 and a connector 212. The plug 211 is plugged into the tube body 10. Specifically, one end of the plug 211 can be plugged into the inside of the tube body 10, and the other end of the plug 211 can be fastened to the connector 212, for example, by adhesive bonding. The end of the connector 212 away from the plug 211 is provided with threads and is fastened to the nursing accessory by the threads.

[0058] In specific implementation, the fixing component 21 may also include only one component, the connector. One end of the connector is covered on the outside of the tube 10 and fixedly connected to the tube 10, for example, by adhesive. The end of the connector away from the tube 10 is provided with threads and is fastened to the nursing accessories through the threads.

[0059] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of an oral observation mirror disclosed in this embodiment. Figure 7 As shown in the illustration, this embodiment also discloses an oral observation mirror 30 for personal care use, used to observe the oral cavity conditions such as teeth and tonsils. The oral observation mirror includes a main unit 31, a lens 32, and a lens connecting tube 100 as described in the above embodiment. The main unit 31 is fixedly connected to the lens connecting tube 100, and the lens 32 is detachably connected to the lens connecting tube 100. In this embodiment, one end of the lens connecting tube 100 is fixedly connected to the main unit 31, and the other end is detachably connected to the lens 32. In specific implementation, the main unit 31 may include a circuit board, a power module, and a communication module, thereby controlling the opening and closing of the lens 32 and sending the image signals collected by the lens to a terminal such as a mobile phone, realizing visualization of the oral cavity condition. Of course, the curvature of the lens connecting tube 100 can also be manually adjusted.

[0060] In an optional embodiment, the oral endoscope 30 further includes a flexible sleeve that covers and encloses the lens connecting tube 100. In this embodiment, since the body 10 of the lens connecting tube 100 has a notch, and the oral endoscope 30 needs to enter the oral cavity, a flexible sleeve is used to cover the outside of the lens connecting tube 100 to protect its structure and facilitate cleaning after use, in order to ensure the service life of the lens connecting tube 100 and the cleanliness and safety of the oral endoscope 30. In specific implementations, the flexible sleeve can be a silicone sleeve.

[0061] Please see Figure 8 , Figure 8 This is a schematic diagram of the structure of a visual ear pick disclosed in this embodiment. Figure 8As shown in the illustration, this embodiment also discloses a visual ear pick 40 for personal care use. The visual ear pick 40 includes a main unit 41, a pick head 42, and a lens connecting tube as described in the above embodiment. The main unit 41 is fixedly connected to the lens connecting tube, and the pick head 42 is detachably connected to the lens connecting tube. In this embodiment, one end of the lens connecting tube 100 is fixedly connected to the main unit 41, and the other end is detachably connected to the pick head 42. In specific implementation, a lens is installed on the pick head 42 to collect image signals from the ear canal. The main unit 41 may contain a circuit board, a power module, and a communication module, thereby controlling the opening and closing of the pick head 42 and / or the bending of the lens connecting tube. It can also send the image signals collected by the lens installed on the pick head 42 to a terminal 50, such as a mobile phone, to visualize the ear canal condition.

[0062] In an optional embodiment, the visual ear pick 40 further includes a flexible sleeve, which covers and encloses the lens connecting tube 100. In this embodiment, since the tube body 10 of the lens connecting tube 100 has a notch, and the visual ear pick 40 needs to enter the human ear canal, a flexible sleeve is placed over the lens connecting tube 100 to protect its structure and facilitate cleaning and disinfection after use, in order to ensure the service life of the lens connecting tube 100 and the cleanliness and safety of the visual ear pick 40. In specific implementations, the flexible sleeve can be a silicone sleeve.

[0063] A lens connecting tube disclosed in this utility model embodiment, used for personal care, includes a tube body for supporting the flexible tube. The tube body has multiple first notches and multiple second notches arranged circumferentially. The first and second notches are staggered circumferentially. The opening directions of the first and second notches are at least partially opposite to those of the second notches, and the first and second notches are not connected. This allows the tube body to be bent in either the opening direction of the first or second notch, enabling bending at multiple angles and improving the flexibility of the lens connecting tube. The widths of both the first and second notches are less than a preset distance, thus limiting the bending angle of the lens connecting tube and preventing structural damage caused by excessive bending, ensuring the safety of the lens connecting tube and extending its service life.

[0064] Those skilled in the art will understand that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0065] It should be understood that the above-described embodiments are merely exemplary and not restrictive. Without departing from the basic principles of this utility model, any obvious or equivalent modifications or substitutions made by those skilled in the art regarding the above details will be included within the scope of the claims of this utility model.
